Tauopathies are a group of neurodegenerative disorders that include hereditary frontotemporal dementias (FTDs) such as FTD with parkinsonism linked to chromosome 17 (FTDP-17), as well as sporadic variants of FTDs like progressive supranuclear palsy (PSP), corticobasal degeneration (CBD), and Pick's disease. These diverse diseases all have in common the(More)
The DOPA decarboxylase gene (Ddc) belongs to the "early-late" class of ecdysone-inducible genes in Drosophila melanogaster. Its expression is up-regulated in epidermal tissues by the ecdysone receptor acting through a response element, EcRE. In this paper, we show that another member of the nuclear receptor superfamily, DHR38, may act as a repressor of(More)
BACKGROUND We describe the brain magnetic resonance imaging (MRI) abnormalities and neuropathologic findings of patients with Sturge-Weber syndrome and medically refractory epilepsy. METHODS We reviewed the clinical features, preoperative MRI studies, and pathologic findings of all patients with Sturge-Weber syndrome who underwent excisional surgery for(More)
CRISPR/Cas9 Overview CRISPRs (Clustered Regularly Interspaced Short Palindromic Repeats) and the CRISPR-associated (Cas) proteins are essential parts of adaptive immune system in bacteria and archaea against invading viruses and plasmids [1-3]. Three types of CRISPR systems exist, of which type II is the simplest one, only requires one Cas protein, Cas9(More)
Abnormal accumulation of TDP-43 into cytoplasmic or nuclear inclusions with accompanying nuclear clearance, a common pathology initially identified in amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), has also been found in Alzheimer’ disease (AD). TDP-43 serves as a splicing repressor of nonconserved cryptic exons and that such(More)
uniform pathological entity [8], and it may involve another yet unknown ubiquitinated pathological protein. A woman with no significant past medical history presented at age 35 with obsessive–compulsive behavior and personality changes and was treated for depression. Her symptoms worsened quickly and she lost her job 6 months later. Magnetic resonance(More)
